In response to TLEberle's question below that started this thread:
On the old 'Concentration.' if you matched a prize (for example, a stove) with a wild card, only those two pieces would be turned around; the other stove card would still be out there, a sitting duck, never to be matched. What happens if you pick the stove and other wild card on the same turn?
TL, I'm old enough to remember the original edition of
Concentration (with the 30-box board), so I can tell you that in this situation, you'd get a second stove on your side of the board!
Theoretically, you could also win
two cars (or whatever that game's most valuable prize was) via this method, or, for that matter, two of any of the other prizes in that game -- although my most remembered game in which this event happened was one in which the contestant ended up with two "Fireflies," one of that game's "gag" prizes that they would have to lessen the pain of matching up any two of the board's six "Forfeit 1 Gift" cards.
Other notes: Late in the NBC run of the show (1958-73), turning around both "Wild Cards" in a player's turn won him/her a new car, plus the chance to turn around two additional numbers for prizes to match with the two "Wild Cards," after which they would go up on the player's prize board. (Pity the player, though, who would turn over a game card for say, a new car, followed by any one of the board's "Forfeit 1 Gift" cards that would immediately send that prize over to the opponent's prize board!)
Also, if the last two boxes on the game board contained non-matching prizes, the player who uncovered the game's last matching pair would have the last chance to guess the puzzle. If he/she failed, the other player would have the last guess of the game, and if that guess failed, the game would end in a tie. (The box game rules, but not those of the studio game, allowed the un-matched prize cards to be removed for a final guess by both players in this situation.)

(Of course now, if the show were still on the air today with the "gag" prizes and the "Forfeit" cards, one of the "gag" prizes for a game might be "500 Cicadas"!)
